framebase[] 是固定的；

你可以试下

我是这样的。
后来用你传的文件里边有一个LCD.C 文件里边的算法显示。显示正常了。但是扫描不出来。。
下边使用的定义 3-1的

unsigned char neccblk1 = 1;
unsigned char neccblk2 = 0;
unsigned char datablkw = 55;
unsigned char eccblkwid = 15;
unsigned char VERSION = 3;
unsigned char ECCLEVEL = 1;
unsigned char WD = 29;
unsigned char WDB = 4;
unsigned char strinbuf[116]="http://www.amobbs.com;http://bbs.yleee.com.cn";
//unsigned char strinbuf[116]="abcdefghijklmnopqrst";
unsigned char qrframe[600];
unsigned char rlens[30];

unsigned char framebase[]  = {
0xfe,0x00,0x03,0xf8,
0x82,0x00,0x02,0x08,
0xba,0x00,0x02,0xe8,
0xba,0x00,0x02,0xe8,
0xba,0x00,0x02,0xe8,
0x82,0x00,0x02,0x08,
0xfe,0xaa,0xab,0xf8,
0x00,0x00,0x00,0x00,
0x02,0x00,0x00,0x00,
0x00,0x00,0x00,0x00,
0x02,0x00,0x00,0x00,
0x00,0x00,0x00,0x00,
0x02,0x00,0x00,0x00,
0x00,0x00,0x00,0x00,
0x02,0x00,0x00,0x00,
0x00,0x00,0x00,0x00,
0x02,0x00,0x00,0x00,
0x00,0x00,0x00,0x00,
0x02,0x00,0x00,0x00,
0x00,0x00,0x00,0x00,
0x02,0x00,0x0f,0x80,
0x00,0x80,0x08,0x80,
0xfe,0x00,0x0a,0x80,
0x82,0x00,0x08,0x80,
0xba,0x00,0x0f,0x80,
0xba,0x00,0x00,0x00,
0xba,0x00,0x00,0x00,
0x82,0x00,0x00,0x00,
0xfe,0x00,0x00,0x00,
};

unsigned char framask[]  = {
0xff,0xff,0xff,0xff,
0xff,0xf8,0x10,0x04,
0x00,0x80,0x08,0x00,
0x40,0x01,0x00,0x02,
0x00,0x02,0x00,0x01,
0x00,0x00,0x40,0x00,
0x08,0x00,0x00,0x80,
0x03,0xff,0x00,0x1f,
0xfc,0x00,0x7f,0xf8,
0x00,0xff,0xf8,0x00,
0xff,0xfc,0x00,0x01,
0xff,0x00,0x00,0x3f,
0xe0,0x00,0x03,0xfe,
0x00,0x00,0x00,
};
下边是从 LCD.C 里边移植过来的代码

QRBIT.H 里边有定义  红 {MOD}的是我参考  QRBIT 修改的

#define QRBIT(x,y) ( ( qrframe[((x)>>3) + (y) * WDB] >> (7-((x) & 7 ))) & 1 )
#define QRBITB(x,y) ( ( framebase[((x)>>3) + (y) * WDB] >> (7-((x) & 7 ))) & 1 )
#define SETQRBIT(x,y) qrframe[((x)>>3) + (y) * WDB] |= 0x80 >> ((x) & 7)
#define TOGQRBIT(x,y) qrframe[((x)>>3) + (y) * WDB] ^= 0x80 >> ((x) & 7)

void DrwBit(unsigned char x1,unsigned char y1,unsigned char X_Long,unsigned char Y_Long,unsigned char *Data)
{
   unsigned char Y_Cout,X_Cout,x,y;
   unsigned char i,k,b,t;

   X_Long=X_Long;
X_Cout = 0;
   Y_Cout = 0;
t = 0;
b = 0;

for(y=0;y<Y_Long;y++)
   {
   for(x=0;x<(X_Long*8);x++)
      {

         b >>= 1;
         if( x <( Y_Long) && y < (Y_Long))

         if( QRBITB(Y_Long-x-1,y) ) b |= 0x80;
         if( ++t > 7 )
               {
                  t = 0;
PutByte(x/8+x1,y+y1,b);

X_Cout ++;
if(X_Cout == X_Long)
{
                  X_Cout = 0;
   Y_Cout ++;
}
                  b = 0;
               }

      }
}
}

直接用  下边函数显示  framebase 就是不正常的图片

void DrwBit2(unsigned char x1,unsigned char y1,unsigned char X_Long,unsigned char Y_Long,unsigned char *Data)
{
unsigned char x,y;
for(y=0;y<Y_Long;y++)
{
   for(x=0;x<X_Long;x++)
   {
   PutByte(x,y,*Data);
   Data ++;
   }
   }
}
